The lottery-winning prisoner serving a life sentence for attempted rape was told by his trial judge that he was a 'menace to women'.
Hoare has been convicted of sex attacks spanning 16 years.
Iorworth Hoare was jailed for life in 1989 for attacking a retired female school teacher in Roundhay Park, Leeds.
Sentencing, Mr Justice Rougier said: "Every moment you are at liberty some woman is at risk."
Hoare, 52, had previously been convicted of a string of sex attacks dating back to 1973.
Hoare, formerly of Seacroft Gate, Seacroft, Leeds, won a reported £7m on the National Lottery at the weekend while on release at a bail hostel.
At his trial in 1988, he denied the attempted rape, claiming police had got the wrong man.
Timothy Bubb, defending Hoare at Leeds Crown Court, said he suffered from an untreatable personality disorder.
But after the verdict, Mr Justice Rougier told the prisoner he was found guilty on overwhelming evidence, adding Hoare showed no signs of psychiatric illness.
"This is the last in a long line of appalling offences committed against women and the only sentence I can pass is one of imprisonment for life," he said.
Hoare's first conviction was for attempted rape in June 1973.
He was jailed for three years at Leeds Crown Court.
In November 1975 he received four years for attempted rape at Exeter Crown Court.
In September 1978 he was given four years for indecent assault and assault at Leeds Crown Court.
And on 15 June, 1983 he was sentenced to seven years at Leeds Crown Court for rape and indecent assault.
He was released on 13 November 1987 - just three months before the attack in Roundhay Park, which happened on 22 February 1988.
